NAME

rex - remote execution

SYNOPSIS

rex [-TAXpv] [-R port:lport] destination [command]

DESCRIPTION

rex is a remote execution facility which is integrated with SFS. The
program allows users run to run programs on a remote machine or obtain
a shell. Like SFS file systems, remote execution servers can be named
by self-certifying path names.
The usage is as follows:
rex [-TAXpv] [-R port:lport] destination [command]
destination is one of the following:
· a self-certifying hostname (location:hostid)
· a self-certifying pathname (/sfs/... or /symlink-to-sfs/...)
· any identifier which when processed through certification programs
will yield a self-certifying pathname

OPTIONS

-T Disable pseudo-tty allocation.
-A Disable SFS agent forwarding. By default, if there is no sfsagent
running on the remote machine, rex will forward agent requests back
to the sfsagent running on the local machine (e.g., when a user
accesses an SFS file system or runs sfskey).
-X Disable X forwarding. By default, the rex client will set up a
dummy X server which receives connections from clients on the
remote machine. These connections are forwarded over the encrypted
rex channel to the local X server. rex sets the DISPLAY
environment variable appropriately on the remote side.
Furthermore, X connections are authenticated using a ‘spoofed’
MIT-MAGIC-COOKIE-1.
-p Force rex to connect to the destination even if it cannot be
resolved into a valid self-certifying path name.
-v Verbose mode.
-R port:lport
Forward TCP connections made to port on the remote host to lport on
the local machine.
The rex command supports the escape sequences listed below. Rex only
recognizes the escape character ‘~’ after a newline.
· . terminate connection
· ^Z suspend connection
· ? help message
· ~ send the escape character
